SEWING-MACHINE.

Specification of Letters Patent.

Application filed July 23, 1902.

Patented Nov. 10, 191%.:

Serial No. 116,613.

To all whom it may concern:

Be it known that we, Lansing ONDERDONK and RUssEL G. 'WooDwARn, cit zens of the United States, residing at New York city,

in the county of New York, State of New York, and \Vaukegan, county of Lake, State of Illinois, respectively, have invented certain new and useful Improvements in Sewing-Machines, of which the following is a ed out in theappended claims.

The invention is illustrated in the accompanying drawings, in wh cl 1- Figure 1 1s a side elevation of a sewlng machine constructed in accordance with our invention; 2 is a cross section taken through the- Qbed of the machine, showing the trimmer, feeding mechanism and presser foot in side elevation. Fig. 3 is a detail perspective View of the presser foot, and stitch forming elements, and illustrating the trimmer knife, and Fig. 4; is a detail view of the presser foot, taken from the opposite side,

from that on which Fig. 3 is taken. Fig. 5 is a perspective view of the stitch finger and its supporting means. p

In these drawings, A is the bed plate, B the standard, C the goose neck, D the needle lever, E the needle bar, F the needle bar' supporting gate or frame.

G is the driving shaft carryin'g in its outer. end the belt pulley H, to which power is applied and through the usual eccentric strap I, motion is transmitted to the needle lever D.

The stitch forming elements of the machine are herein shown as comprising the vertically reciprocating thread carrying eye pointed needle 1, which carries a thread down through the material, and in 1ts upward movement throws out a. loop, which loop is seized by a spreader or looping hook S and carried laterally to a point above thecloth plate of the machine, where it is engaged by an oscillating looper L mounted on a shaft M supported entirely above the cloth plate of the machine, which shaft is oscillated to carry a loop of thread through the needle loop and into positionto be engaged by the needle in its next descent.

The feeding mechanism is shown clearly 1n F1g. 2 and it is desirable in machines of this character to crowd the goods toward the needle before the stitching takes place to prevent puckering after the stitches havev been passed through the fabric, and the feed dog 29 is, therefore, inclined, and so ranged that as it is lifted that part of it;

ahead of the needle will catch the goods first. The inclination of the feed dog may be varied, as desired, .n echanism not necessary to herein specifica' yfdescribe.

The trimming device is arranged to act ahead of the stitch forming mechanism to trim of? the edge of the fabric to prepare "said edge for the reception of the stitches and in the present machine the trimmer com rises an upper reciprocating trimmer kni e and a lower cooperating stationaryway and is normally depressed by the spring '95, which bears on the angle piece 90 pivoted to the shank of the presser foot, the spring 95 being attached to the screw 96 passing through the arm 97 projecting from the presser foot shank.

A tongue 98 over which the stitches are formed, is rigidly attached through the upwardly extending plate 92 and screw 99, to the presser foot shank. It will be seen, therefore, that the forward spring pressed end of the presser foot coacts with the inclined feed dog and that in the operation of the machine, stitches are formed over the tongue 98 which does not partake of the rocking movement of the bottom or shoe of the foot and are fed 0H said tongue, in the plate 100, having a slot 101 for the passage of the knife, and having a deflecting rear portion 102 which, as the presser foot moves vertically under the action of the feed dog, will crowd the trimmed off strip down through the opening in the cloth plate through which the waste material passes off the plate of the machine.

Various minor modifications and changes in the construction of the parts may be made, without departing from the spirit of our invention.

Having thus described our invention, what we claim and desire to secure by Letters Patent, is

1. In an overseaming machine stitch forming mechanism including means for carrying a thread laterally across the seam, a presser foot having a hinged foot portion and a rigid tongue independent of the hinged portion over which the stitches are formed; substantially as described.

2. A11 overseaming machine including means for carrying a thread laterally across the seam, anda resser foot having a hinged spring pressed orward portion and a rigid tongue independent of the spring pressed forward portion, over which the stitches are formed; substantially as described.

3. An overseaming machine, .stitch forming mechanism, including means for carrym a 'pr%sser foot having ahinged spring pressed forward portion and having a rigid tongue secured to the shank of the presser foot and independent of the spring pressed forward portion; substantially as described.

4. An overseaming machine including in combination, means for carrying a thread laterally across the seam, a presser foot including a forward portion, means for pivotally supporting the same, yielding means for holding said forward portion in contact with the material, and a feed dog inclining downwardly from front to rear, and adapted to engage the material in advance of the needle and crowd it toward the same, said operate with the forward plvoted portion 0 said presser foot.

5. An overseaming machine including 1 stitch forming mechanism having means for carrying a thread laterally across the seam, a presser foot including a forward portion, means for supporting the same,

and means for holding said forward por-- tion yieldingly in contact with the material, an inclined feed dog with whichsaid yield 1 ing also a transverse deflectin thread laterally across the'seam, a

for adjusting the spring; described.

inclined feed dog being so disposed as to .co-

tures, in presence of two witnesses.

ing forward portion of the presser foot coacts, and a rigid tongue independent of the yielding forward portion of the presser foot over which the stitches are formed.

6. In a sewing machine having a cloth plate provided with an opening, the combination with a trimmer, and a feeding device, a presser foot having a pivoted front portion provided with a deflector which 0 erates as the presser foot falls with the eed to force the trimmed ofi' strip out of the line ofthe seam through said opening; substantially as described.

7. A sewing machine presser foot having a rigid shank with stitches are formed secured thereto, a pivoted forward portion which cooperates with the feed, said portion being normally spring pressed downwardly, said presser foot havplate to defiect the trimmed ofl strip ;su stantially as described.

8. The herein described presser foot, comprising'the rigid shank, the forward portion hinged thereto in rear of the needle, a

pivoted armbearing upon the pivoted portion in advance of the needle, a spring bearing upon said pivoted arm; substantially as described.

9. The herein described presser foot, comprising the rigid shank, the forward portion hinged thereto in rear of the needle, a pivoted arm bearing upon the pivotedportion in advance of the needle, a spring bearing upon which the stitches are formed, rigidly attached to the presser foot shank; substantially as described. I

10. The herein described presser foot, comprising the rigid shank, the forward portion hingedthereto in 'rear of the needle, a pivoted arm bearing upon the pivoted portion in advance of the needle, a spring bearing upon said pivoted arm, and means substantially as In testimony whereof we affix our signa- LANSING ONDERDONK.
